Provider support for optimizer overrides in Derby.
--------------------------------------------------
Key: DERBY-573
URL: http://issues.apache.org/jira/browse/DERBY-573
Project: Derby
Type: New Feature
Components: SQL
Versions: 10.2.0.0
Reporter: Mamta A. Satoor
Assigned to: Mamta A. Satoor
Derby's query optimizer usually makes the best choice of join order and access
path. The default join strategy ususally works the best too. However, there are
some cases in which user may want to override the optimizer or the default
values. Providing support for optimizer overrides will allow users to hand-tune
the optimizer for queries.
